Original application led August 13, 1918, Serial No. 249,646. Divdedandthis application led December T0 all whom 'it may concern:

Be 1t known that we, FRANK STREICH and V PAUL B. STRnIcI-r, citizens ofthe United Aplan and partly in States, and residents of Joliet, l/Villcounty, and State oflllinois, have invented certain new and usefulImprovements in Bucket- Dumping Mechanism for Conveyers of ProofingApparatus, of which the following is declared to be a full, clear, andexact description.

This invention relates to bucket dumping mechanism for conveyers ofproofing appa ratus, one form of which apparatus is shown and describedin our prior application for patent filed August 13, 1918, Serial No.249,646, from which this application has been divided.

rIhe principal objects of this invention are to provide automatic meansfor tilting the buckets of the conveyer at the discharge end of theapparatus; to provide automatic means for insuring the discharge of thelumps of dough from the 4buckets and to provide automatic dumpingmechanism which maybe readily made inactive, whereby the buckets maypass by the dumping mechanismwithout being affected thereby. With theseand other ob]ects in view, this invention consists in the several novelfeatures 'hereinafter fully set forth and particularly defined in theclaims.

The invention is clearly illustrated in the drawing, accompanying thisspecification, in

which:

Figure 1, is a View partly in side elevation and partly in vertical,longitudinal section of a fragment of a proofing apparatus, containingconveyer mechanism and showing a simple embodiment of the bucket dumpingmechanism, forming the subject matter of this application; Fig. 2, is aview partly in horizontal section of the parts seen in Fig. l; Fig. 3,is a detail, vertical cross section taken on the line 3-3 of Fig. 2;Fig. 4, is a fragmental, side elevation, partly broken away andillustrating` a modification of the invention and Fig. 5,*is a verticalcross section taken-on the line 5--5 of Fig. 4.

Referring to said drawing, the reference character 27a, designateshorizontal, lengthwise extending, frame members of the proofing chamber,39 designates upright frame Serial No. 266,549.

members and 36 designates horizontal, transverse, frame members. Theupright members 39, divide the structure into a series, of panels inwhich are secured glazed doors 32. Bottom walls 35, are secured to theframe Ymembers 27, and are in the form of doors which may be openeddownwardly; they are held in closed position by locks or latches 38.'a Adischarge opening is left at ai, through which opening the lumps ofcharged from the apparatus. All of the parts-thus far described are moreparticularly set forth in the application, above referred to.

Secured to the upright frame members 39, are horizontal parallel tracks59, here shofwn in the form of angle iron bars", and said tracks supportthe traveling, endless conveyer. In the form of conveyer hereinillustrated, dough carrying buckets 44, are employed which areYarranged'in pairs, and those of each pair connected byl a rod 53, se-

- cured in ears 55, of the buckets. Rollers 58,

are journaled on ears 57 ofthe buckets and travel upon Vthe tracks 59.An endless'conveyer belt 43, is employed for moving the buckets throughthe prooi-ing apparatus and said conveyer belt extends between thebuckets of each pair and connected to 'they rods 53,'by clips 54. Therods are loosely held in the clips so that the buckets are free torotate with respect to the belt in order that they may be suspended inan upright position irrespective of the fact that the belt 43 travelsaround pulleys in the chamber of the roofing apparatus as is clearly setforth inour prior application. Y'

At the discharge opening .'L, cam blocks 11.7 are provided, which cam'blocks are shown as secured to the tracks 59, and lie in the path oftravel of the rollers 58; cani blocks have upwardly inclined faces 118over which the rollerstravel in discharging the dough from the buckets.Extending laterally from the cam blocks 117, are projections, here shownin the form of rollers 119, that liein the path of travel of the upperedges 44a of the buckets and said rollers areso positioned with respectto the inclined faces 118 'of the cam blocks as to engage said edges442, while the Vbucket rollers 58, travel up said'inclined faces'118,therebyV tilting said buckets backward far enough to dough are dis- YSaid invert them; and, permitting the dou-ghto fall out of diebucketsvTo insure the dis# charge of the dough from the buckets, in case thedough sticks to the buckets, pins or 5 other projections 119C, aresecured tothe cam blocks adjacent thel rollers-119, `which pins arepositioned to be forcibly engaged bythe edges 44a of the buckets afterthe inverted buckets drop away from the rollers 119. In case a lump ofdough clings t0 the bucket, the jar occasioned by the fall of the bucketuponthe pin 119C, will serve to releasethe lump of dough from thebucket.

In the form of the invention illustrated in Figs. t and 5, the cam block1172*, vis movably mounted with respect to the track 59, whereby it maybe moved outl of the path of movement of the bucket rollers 58, and

thereby may be rendered inactive. This form of the invention may be usedat any place in the proofing apparatus where itis desired to dischargethe lumps kof dough from the buckets, y.before reaching the permanentbucket dumping mechanism illustrated in Figsrl to 3 inclusive. In saidmodified form, each-cam blockll'a, is carried, by an arm120, which ismounted upon a rock shaft 122, journaled in bearing brackets12l, whichare mounted upon the frame members 27 a.' As; in the preferred form,there are two cam blocks, one at eachV track 59, and the armsvof bothcam'blocks are mounted upon the rock shaft 122. An operating handle 123,vis mounted upon the outer end of said rock shaft and has a lug 125,

which contains afspringfpressed latch 124, arranged to engage'withrecesses126, 127, formed in the outer face ofthe side frame member 27ai. 'As in the preferred form, the 40 cam blocks may be provided withpins, one of which is shown at 119,forfjarring the buckets after theyhave passed the frollers 1:19a. In Fig. 4;', the operative position oflthe bucket dumping mechanism is shown in i full lines and when it isdesired to render it inactive, the handle 123, is swung to the rightuntil the-.latch engages inthe recess 127, the rock shaftrand both camblocksare thereby moved to theposition seen. indotted linesV in Fig. 4f.j

In the'operation of the device, the con- 'veyer is moved inthe directionindicated by the arrow in Figs. l-'and 2, and. when the buckets reachthe cam blocks117,.the rollers v 58, travel up the inclined faces118 ofsaid cam blocks, as seen in dotted lines in Fig. 1, whilethe edgesillla,of the buckets engage lthe-rollers;- 119, which acty as fulcrums over j"which the buckets arey tilted into an inverted.l positlon as seen inFig. "1, -.thereby .permit- Y ting `the dough to be dischargedtherefrom.Y

VAfter the buckets' pass the rollers 119, they v drop upon thepins119,,VV and are, thereby/ L jarred sufiiciently .to release a lump ofdough, 1n case it adheres to the sides or bottombf the bucket. Afterpassing the pins 119C, the buckets resume their uprightmcarryingposition. rEhe dough is discharged through the opening m, andfalls upona table, conveyer or the like, from which sit 1s 7g removed to therounding up machine or. other bakers machinery.

Moreor less variation of the exact details of construction is possibleWithout ldeparting from the spirit' of this invention. We 75 desire,therefore, not to limit ourselves to the exact forinof the constructionshown and described, but intend, in the following claims, to point outall of the invention disclosed herein. f f 80 We claim as new, anddesire to secure by Letters Patent: 'j
